Four-dimensional model representing health locus of control. Model 4a included latent variables Internality (Internal), Formal Help (Formal), Informal Help (Informal) and Externality Chance (Chance). Correlations among latent variables, factor loadings and measurement errors of indicators were calculated, while variances of latent variables were fixed to one. Note that items 12 and 17 of the German questionnaire to survey control beliefs concerning disease and health (KKG) by Lohaus and Schmidt (1989) [37] were not included in Model 4a.
